Researchers have found that Eucalyptus trees (gum trees) can help in finding gold reserves under earth as these trees have the ability to move up the gold particles from the earth and deposit them in the leaves and branches.
These are tall evergreen trees having tough aromatic leaves and flowers in clusters and provide good timber, resin, and oil with medicinal properties. There are more than 600 species. Read more…
Researchers have found that ants and termites could help us to find the hidden treasures such as gold in the Earth.
This research has been conducted by CSIRO and published online in the journals PLoS ONE and Geochemistry: Exploration, Environment, Analysis.
Researchers have worked on a test site in the West Australian goldfields termite mounds and found high concentrations of gold that could represent larger deposit underneath.
“We’re using insects to help find new gold and other mineral deposits. These resources are becoming increasingly hard to find because much of the Australian landscape is covered by a layer of eroded material that masks what’s going on deeper underground,” Dr Aaron Stewart, CSIRO entomologist said.
Researchers found that the termites and ants snug the places by digging in the material, where gold traces were found underlying and bring the traces to the surface.
“The insects bring up small particles that contain gold from the deposit’s fingerprint, or halo, and effectively stockpile it in their mounds,” Dr Stewart said.
“Our recent research has shown that small ant and termite mounds that may not look like much on the surface, are just as valuable in finding gold as the large African mounds are that stand several metres tall.”
Dr Stewart also discovered that the insects also carry metals in their bodies. Read more…
Eldorado Gold Corp., Canadian Gold and Iron Producer, said on Sunday that it has agreed to purchase European Goldfields Ltd., a Yukon based small rival company and gold miner with projects in Greece, Romania and Turkey, in a cash and shares deal of C$2.5 billion (US$2.4 billion), in order to expand its business opportunities in the production of gold and other precious metals. It is the Canadian company’s biggest acquisition. However, the deal comes at such time when the gold prices are trading close to record high values.
Detection of disease at an early stage is one of the biggest challenges in medicine. Different fields of science are working together in this regard.
Scientists from India have developed a nanosized probe that will be very helpful for early detection of diseases. The research was published in September 6th issue of The Journal of Physical Chemistry C.
Researchers have designed a magnetofluorescent hybrid probe. They have combined the magnetic and optical properties in hybrid nanoparticles, which are thought to be the versatile type of probes. This combination of properties helped scientists to detect, image and separate cells as well as molecules. Read more…
DNA sensors for disease detectionhave been improved by the Scientists of China.
DNA sensors can help in detection of genetic and pathogenic diseases as they bind to particular DNA strands that are linked to the disease by giving a response of the amount of the DNA. Read more…
